Chemical Structure

2,2,2-Trifluoroethyl 4-methylbenzenesulfonate CAS 433-06-7 chemical structure

Description

Based on its molecular formula C9H9F3O3S, 2,2,2-Trifluoroethyl 4-methylbenzenesulfonate contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 254.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

2,2,2-Trifluoroethyl 4-methylbenzenesulfonate (CAS 433-06-7), molecular formula C9H9F3O3S and molecular weight 254.23 g/mol, is a CATO reference standard with documented purity and traceability.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
